Imagine if you had the opportunity to unveil one of the universe’s biggest mysteries—dark matter. Scientists are attempting just that with experiments at the Large Hadron Collider (LHC). Dark matter is an unseen force that holds galaxies together, yet it’s still invisible to us. Researchers are exploring the possibility of detecting it through the Higgs boson and other particles in the collider.
The latest research focuses on detecting a unique signal known as the ‘mono-Higgs’ using a method called Effective Field Theory. By studying how dark matter might interact with particles we can see, like the Higgs boson, scientists are becoming increasingly confident that they might soon reveal the hidden nature of dark matter. They utilize highly sophisticated techniques to differentiate this signal from other noise at the LHC, and the possibility of discovering dark matter is more real than ever.
Why does this matter in your everyday life? Imagine knowing more about the stuff that makes up 85% of the universe’s mass! Discovering dark matter could lead to groundbreaking technologies and a deeper understanding of the cosmos, which might eventually affect technologies and sciences that impact us all. By studying this unseen world, we’re not just looking to the corners of the universe but potentially opening doors to unforeseen advancements right here on Earth.
Did you know that dark matter makes up about 85% of all the matter in the universe, but we still can’t see it with any of our current technology?

Background
Dark matter is a mysterious form of matter that doesn’t emit, absorb, or reflect light. It’s inferred to exist because of its gravitational effects on visible matter, like stars and galaxies. The Large Hadron Collider is a particle accelerator that collides protons to analyze high-energy physics phenomena. Scientists use Effective Field Theory to study potential interactions that dark matter particles might have with known particles by introducing hypothetical particles or interactions to fit current experimental data.
History
The existence of dark matter was first proposed in the 1930s to explain gravitational effects that couldn’t be accounted for by visible matter alone. Over the decades, our understanding of dark matter has evolved, thanks in part to cosmological observations and experiments at particle colliders. The Higgs boson, discovered in 2012, plays a crucial role in particle physics, as it is thought to give particles mass. Recent research builds on these discoveries, using the LHC to further explore possible interactions between the Higgs boson and dark matter.
